Revisiting Fat Graft Harvesting and Processing Technique to Optimize Its Regenerative Potential.

Background: The use of fat grafting has expanded to include cell and tissue regeneration, necessitating investigations to ensure the viability of stromal and adipose-derived mesenchymal stem cells (ASCs) within the transferred fat parcels. This study explored the impact of harvesting technique and centrifugation on the viability of stromal cells and ASCs in lipoaspirate.

Methods: Fat was harvested from patients undergoing fat grafting using 2 types of liposuction cannula: (A) a 3-mm blunt tip cannula with 3 smooth holes and (B) a 2.

Wound healing in stage IV pressure injury with use of adjunct autologous activated platelet-rich plasma therapy: a case report.

Introduction: Pressure injuries remain a major burden worldwide with associated morbidity and financial implications. Patients in the ICU, such as those with severe COVID-19, are especially susceptible to PI as they remain immobile for extended durations while intubated.

Objective: This report examines a case of stage 4 PI in a senior COVID-19 survivor treated with adjunct intravenous and intralesional aaPRP therapy in addition to topical hyaluronic acid/silver sulfadiazine cream and framycetin sulphate dressing.

Therapeutic Effect of Autologous Activated Platelet-rich Plasma Therapy on Mid-dermal to Full-thickness Burns: A Case Series.

Although modern medicine has made great strides in the management of burn injuries, associated complications such as pain, infection, dyspigmentation, and scarring have yet to be fully dealt with. Although skin grafting and meshing are routinely performed on burn patients, this method poses a risk for adverse effects. Activated autologous platelet-rich plasma (aaPRP), which is increasingly used in the field of plastic surgery, contains growth factors beneficial for wound regeneration.

Free flap thrombosis in patients with hypercoagulability: A systematic review.

Background: Even with satisfactory anastomosis technique and adequate experience of the surgeon, flap loss due to thrombosis can still occur due to the patient's underlying condition. Patients with hypercoagulability due to etiologies such as malignancy, hereditary conditions, and acquired thrombophilia are among those who could benefit from free flap procedures. This review aimed to evaluate the risk of free flap thrombosis in patients with hypercoagulability and to identify the most effective thromboprophylaxis regimen.

Experimental Study of Tumescence Injection to Provide Anesthesia Without Local Anesthetics.

Background: One-per-mil tumescent technique could provide local anesthesia in surgical procedures despite using low lidocaine concentration. Tumescence environment within the tissue may play a role in supporting local anesthesia effect. This study aims to delineate whether the tumescence environment, created by one-per-mil solution without a local anesthetic agent, had a local anesthesia effect.

One-per-mil tumescent technique for upper extremity surgeries: broadening the indication.

Purpose: We studied the effect of 1:1,000,000 epinephrine concentration (1 per mil) to attain a bloodless operative field in hand and upper extremity surgery and to explore its effectiveness and safety profile.

Methods: This retrospective observational study enrolled 45 consecutive patients with 63 operative fields consisting of various hand and upper extremity problems. One-per-mil solution was injected into the operative field with tumescent technique to create a bloodless operating field without tourniquet.
